A notice invoking arbitration is the written request under Section 21 of the Arbitration and Conciliation Act, 1996 by which one party asks the other to refer a dispute to arbitration, and arbitral proceedings commence on the date the other party receives it. The Act prescribes no format, but the notice must identify the parties, refer to the arbitration clause, set out the dispute, propose an arbitrator, and fix a period to reply. In January 2026, the Supreme Court held that failure to issue the notice is not by itself fatal to a claim that is otherwise valid and arbitrable, though the notice remains the step that fixes limitation and precedes an application to appoint an arbitrator.
This article sets out how to draft a notice invoking arbitration, what the courts now require of it, and how to reply to one.
The notice is the only document in an arbitration whose date does real legal work on its own. Everything downstream, the limitation position, the ninety-day window under Section 9(2), the right to move a court for appointment, is measured from the moment it lands. Get the drafting right and those dates take care of themselves.
Most fights about Section 21 notices aren’t really about the notice. They’re about limitation, and the notice happens to be where the clock stopped. That’s why a defective notice tends to surface two years later, in a jurisdictional application, when nobody can fix it.
The drafting itself is not complicated. There’s no prescribed form, no schedule to fill in, no filing fee. What it demands is precision about five things, and the discipline to say nothing beyond them.
Essence of a notice invoking arbitration
A notice invoking arbitration is a written request from one party to another asking that a particular dispute be referred to arbitration. Section 21 of the Arbitration and Conciliation Act, 1996 gives it its only statutory function: unless the parties have agreed otherwise, arbitral proceedings in respect of a particular dispute commence on the date on which a request for that dispute to be referred to arbitration is received by the respondent.
Read that again, because the operative word is received. Not sent, not signed, not dispatched by courier. The date your notice leaves your office is legally irrelevant. The date it reaches the other side is the date your arbitration begins.
Note the opening words too: “unless otherwise agreed by the parties”. Parties can contract out of the default rule and fix a different trigger in the clause itself. Most standard commercial clauses don’t, but institutional rules sometimes do, so check the clause before you assume the statutory default applies.
The Act says nothing about what the notice should look like. No format, no mandatory recitals, no prescribed length. That silence is the source of most drafting anxiety and nearly all defective notices. Practitioners fill the vacuum by importing habits from other documents, and that’s exactly where things go wrong.
So what is it not? It isn’t a statement of claim, and loading it with evidence and legal argument helps your opponent more than it helps you. It isn’t a contractual demand notice under a payment or cure clause (those are creatures of the contract, not the statute, and one does not do the other’s work). And it isn’t an application under Section 8 asking a court to refer parties to arbitration. A Division Bench of the Delhi High Court dealt with that conflation in Web Overseas Ltd. v. Universal Industrial Plants Manufacturing Co. Pvt. Ltd. (28 November 2022), holding that a Section 8 application “is not a substitute of a notice under Section 21”, because the two do entirely different things: Section 8 asks a court to step back, while Section 21 starts the clock.
One more piece of housekeeping. You’ll meet this document under four names: notice invoking arbitration, notice of arbitration, Section 21 notice, and notice of commencement. Same instrument. The variation is habit, not law. Whichever name your clause uses, the drafting obligations are identical, and they start with the arbitration agreement you’re invoking.
The Section 21 clock: what receipt of the notice actually starts
Arbitration and Conciliation Act, 1996
Notice drafted
No legal effect. The date typed on the notice does nothing at all.
Notice served
Still nothing. Dispatch is not the trigger.
NOTICE RECEIVED
Arbitration commences (Section 21). Limitation stops running. The Section 9(2) ninety-day clock is measured from this date, not from appointment of the arbitrator or filing of a Section 11 petition (Regenta Hotels, SC, 2026).
+ 30 days
Respondent’s window to agree on the arbitrator. Thirty days from receipt is the statutory default under Section 11(4) where the clause is silent.
After 30 days
Claimant may apply to the court under Section 11 for appointment of an arbitrator.
The point: receipt, not dispatch, is the operative event. Your proof of service is your proof of commencement, so keep the acknowledgement due card and the delivery report.

Why the notice matters
The notice matters because it fixes the date from which almost every other deadline in the arbitration runs. Three consequences follow from receipt, and each of them can decide a case.
Limitation. Arbitration claims are governed by the Limitation Act, 1963, and the clock stops on the date of commencement under Section 21. Take a breach on 15 June 2025 on a three-year limitation period. A notice received on 24 February 2026 stops the clock with room to spare. The same notice, drafted in June 2028 and received in July, is a dead claim, and no amount of correspondence in between saves it. This is where most claimants go wrong: they treat months of demand letters, reminders and without-prejudice meetings as though those preserve the claim. They don’t. Only receipt of the Section 21 request does.
Interim relief under Section 9(2). Where a court grants interim relief before arbitration begins, Section 9(2) requires that arbitral proceedings commence within ninety days of the order (or such further time as the court allows). Ninety days from what, exactly? The Supreme Court answered that in Regenta Hotels Pvt. Ltd. v. Hotel Grand Centre Point, 2026 INSC 32, decided on 7 January 2026. Statutory consequences tied to commencement must be assessed solely with reference to the date of receipt of the Section 21 request, and not the date an arbitrator is appointed or a Section 11 petition is filed. A party sitting on an injunction while it prepares a Section 11 petition is burning its ninety days. The relevant date passed the moment the notice was received, or never started because it was never sent. If you’re weighing interim relief under Section 9 against Section 17, this is the timing point that decides the sequence.
The Section 11 gateway. When the other side ignores your nominee or proposes someone unacceptable, your route is an application to the court under Section 11. The notice is what evidences the failure of the agreed appointment procedure, and courts expect to see it before they entertain the application. Without it, you’re asking a court to fix a problem you haven’t shown exists. The mechanics of that route are set out in the post on Section 11 of the Arbitration and Conciliation Act, 1996, and LawSikho’s walkthrough of Section 11 and the appointment process covers the drafting of the petition itself.
There’s a fourth point, and it cuts the other way. The notice frames the dispute, but it does not cap it. More on that in the next section, because it’s the part of the law that changed.
What the courts now require of a Section 21 notice
Here’s where the ground has shifted, and where most published guidance is still standing on the old map.
The settled position, until recently. The Delhi High Court in Alupro Building Systems Pvt. Ltd. v. Ozone Overseas Pvt. Ltd., 2017 SCC OnLine Del 7228 (28 February 2017) held that a Section 21 notice was a mandatory precondition, and that arbitral proceedings commenced without one were unsustainable. A party had unilaterally appointed a sole arbitrator without any request to the other side. The award was set aside on a Section 34 challenge, though on three independent grounds and not this one alone: there was no valid arbitration agreement, no Section 21 notice, and the arbitrator had failed to disclose. Worth flagging, because most summaries skip it: the court also accepted that the Section 21 requirement can be waived by agreement between the parties. The Bombay High Court took a similar view of the section in Malvika Rajnikant Mehta v. JESS Construction Pvt. Ltd. (28 April 2022), holding that the notice is mandatory and isn’t waived merely by naming an arbitrator. And the Calcutta High Court in West Bengal Power Development Corporation Ltd. v. Sical Mining Ltd., 2022 SCC OnLine Cal 3036 (30 September 2022) dismissed a Section 11 application as premature where no notice had been issued, with liberty to serve one. Read together, they produced a rule most practitioners can recite: no notice, no arbitration.
The 2026 correction. On 5 January 2026, a Division Bench of Justices J.B. Pardiwala and K.V. Viswanathan decided M/s Bhagheeratha Engineering Ltd. v. State of Kerala, 2026 INSC 4. A contractor had four disputes arising from Kerala road maintenance packages. It took one through the contractual adjudication route and into arbitration, but never issued a separate Section 21 notice for disputes 2, 3 and 4. The Kerala High Court held that omission fatal and set the award aside on that ground alone.
The Supreme Court disagreed, in terms that leave little room for argument. There is no mandatory prerequisite for issuance of a Section 21 notice prior to the commencement of arbitration. Failure to issue it, the Court held, “would not be fatal to a party in arbitration, if the claim is otherwise valid and the disputes arbitrable.” Section 21 is procedural rather than jurisdictional. Its work is fixing commencement for limitation, and it does not condition the tribunal’s authority to decide claims that weren’t itemised at the threshold. The award was restored in its entirety.
The Court added a second point with real drafting consequences: a claimant is not confined to the claims raised in the pre-arbitration notice, and claims and counter-claims can be amended before the tribunal. Your notice is an opening position, not a pleading you’re stuck with.
Reconciling the two lines. Nine months earlier, in Adavya Projects Pvt. Ltd. v. Vishal Structurals Pvt. Ltd., 2025 INSC 507, decided 17 April 2025, the Supreme Court had described the Section 21 notice as mandatory, noting that it fixes the date of commencement and precedes a Section 11 application. Yet it held that non-service on a particular person did not prevent that person being impleaded before the tribunal, because jurisdiction flows from consent to the arbitration agreement, not from procedural compliance.
Do the two decisions collide? Not really. Put side by side, they describe the same architecture from different angles.
The practitioner’s takeaway
Section 21 is a limitation trigger, not a jurisdictional gate. That single sentence reconciles Adavya and Bhagheeratha, and it should govern how you advise.
What it does not mean is that notices are now optional. Bhagheeratha is a shield for a claimant whose notice was defective, incomplete, or missing for some disputes but not others. It’s not a licence to skip the step. Skip it and you forfeit your limitation anchor, you lose the Section 9(2) computation, and you hand the other side a clean procedural objection that costs money to defeat even when you win. The practical reality is that the cost of issuing a notice is one afternoon’s drafting, and the cost of not issuing one is litigating Bhagheeratha for two years to find out whether your claim was “otherwise valid”.
Issue the notice. Every time, for every dispute you intend to raise. Treat the January 2026 ruling as insurance against your own error, not as a plan. For the doctrinal detail of the provision itself, the post on Section 21 of the Arbitration and Conciliation Act, 1996 goes deeper into the section’s scope and objects than this drafting guide needs to.
Anatomy of a notice invoking arbitration
Nine particulars, and what omitting each one costs you
#
Element
What it must say
Cost of omitting
1
Parties
Names, registered address, and the service address specified in the agreement
Service becomes arguable
2
The agreement
Date, parties, purpose. One sentence
Dispute cannot be located in a contract
3
The arbitration clauseFATAL
Clause number, reproduced verbatim, with the word “invokes”
Fatal on its own. The Alupro error: no request to refer was ever made
4
The dispute
Facts, breaches, dates. Identifiable, not argued
No identifiable dispute is referred
5
Quantum
Approximate monetary value of the claim
Limitation cannot be tested
6
The arbitrator
Nominate and call for confirmation. Never appoint
Unilateral appointment risks the award (Alupro)
7
Seat and venue
Exactly as the clause provides, stated separately
Wrong supervisory court
8
Time to reply
15 to 30 days from receipt
No trigger for the Section 11 route
9
Reservation of rights
Express statement that the notice is issued under Section 21
Argument that it was only a contractual demand
Minimum content: only element 3 is fatal standing alone. A reference to the arbitration clause plus an unambiguous statement that you are invoking it is what makes the document a Section 21 request. Everything else is craft.

Particulars the notice must carry
The particulars a notice must carry are dictated by function, not by any statutory schedule. Each element earns its place by doing a job: identifying the source of the tribunal’s authority, fixing the date, or forcing a response.
Work through these in order when you draft:
- The parties. Full names, registered addresses, and the address specified in the agreement for service. Add counsel details if you’re on record.
- The agreement. Date, parties, and purpose. One sentence.
- The arbitration clause. Clause number, reproduced verbatim. This is the single element you cannot omit. It is the source of the tribunal’s authority, and a notice that never points to it is asking the recipient to guess.
- The dispute. Facts, breaches, dates. Enough to make the dispute identifiable, not enough to argue it.
- Quantum. An approximate monetary value of the claim. Vague quantum invites a limitation challenge you can’t answer, because nobody can test when a claim arose if nobody can say what it is.
- The arbitrator. A nomination, with any qualification the clause requires. Propose. Never purport to appoint.
- Seat and venue, exactly as the clause provides. Confusing the two is the most common drafting error in Indian arbitration notices, and the distinction between seat, venue and place decides which courts supervise your arbitration.
- Time to reply. Fifteen to thirty days is standard. Where the clause is silent on appointment, Section 11(4) allows thirty days from receipt before you can move the court, so a fifteen-day reply window doesn’t accelerate anything.
- Reservation of rights, and an express statement that the notice is issued under Section 21.
Item 3 deserves emphasis. In Alupro, the court’s objection wasn’t that the notice was badly written. It was that no request to refer had been made at all. The minimum content of a valid Section 21 request is a reference to the arbitration clause and an unambiguous statement that you’re invoking it. Everything else is craft.
Is any of this a form you can fill in? No, and that’s the point. The particulars are dictated by the three jobs the notice has to do, which is why a notice copied from a precedent bank tends to carry paragraphs that serve neither.
How to draft a notice invoking arbitration
The drafting is best learned against facts. Here’s a worked scenario, then the notice itself, annotated block by block.
The scenario
Meridian Foods Pvt. Ltd. manufactures frozen ready-to-eat products. On 12 March 2023 it entered into a Warehousing and Distribution Agreement with Northline Logistics Pvt. Ltd. Under Clause 9, Northline was to maintain an unbroken cold chain at minus eighteen degrees Celsius through storage and transit, and to furnish temperature logs for every consignment.
Between June and September 2025, eleven consignments recorded temperature excursions. Meridian’s retail customers rejected the stock. Meridian put the losses at Rs. 3,20,00,000 and wrote to Northline in October and again in December 2025. Northline denied the logs were reliable and demanded its withheld service fee of Rs. 1,08,00,000.
On 3 February 2026, Meridian obtained an ad-interim order under Section 9 restraining Northline from releasing the remaining stored consignments pending arbitration. That order started a ninety-day clock. Clause 19 of the agreement reads:
“Any dispute arising out of or in connection with this Agreement shall be referred to and finally resolved by a sole arbitrator appointed in accordance with the Arbitration and Conciliation Act, 1996. The seat of arbitration shall be New Delhi and the venue shall be Gurugram. The award shall be final and binding on the parties.”
Meridian is the claimant. The notice must go out and, more to the point, must be received well inside ninety days of 3 February 2026.

[ON THE LETTERHEAD OF THE ADVOCATE / LAW FIRM]
BY REGISTERED POST A/D AND BY EMAIL
To,
Northline Logistics Pvt. Ltd.
[Registered office address as per the Agreement]Date: 20 February 2026
The mode of service is stated on the face of the notice, and it tracks what Clause 24 of the agreement permits. You’re building your proof of receipt into the document itself.
Subject: Notice invoking arbitration under Section 21 of the Arbitration and Conciliation Act, 1996 read with Clause 19 of the Warehousing and Distribution Agreement dated 12 March 2023
The subject line does three jobs at once: it names the statute, it names the clause, and it identifies the agreement. A recipient who reads nothing else knows exactly what has arrived. Never head this “Legal Notice”. That invites the argument that you sent a contractual demand rather than a Section 21 request.
Dear Sir/Madam,
- We act for Meridian Foods Pvt. Ltd., having its registered office at [address] (hereinafter “our Client”), and are instructed to address you as follows.
Identify your client and your authority in the first paragraph. Nothing else belongs here.
- Our Client is engaged in the manufacture of frozen ready-to-eat food products. You are engaged in the business of warehousing and distribution, including temperature-controlled storage.
Two sentences of context. Resist the temptation to write a company profile.
- By a Warehousing and Distribution Agreement dated 12 March 2023 (“the Agreement”), our Client engaged you for temperature-controlled storage and distribution of its products.
The agreement, identified by date and defined for the rest of the notice.
- Under Clause 9 of the Agreement, you were obliged to maintain an unbroken cold chain at minus eighteen degrees Celsius through storage and transit, and to furnish temperature logs for each consignment.
Point to the obligation breached, by clause number. One clause, one paragraph.
- Between June and September 2025, eleven consignments dispatched from your facility recorded temperature excursions above the contractual threshold. The affected stock was rejected by our Client’s retail customers. Our Client’s losses on account of the said spoilage are approximately Rs. 3,20,00,000 (Rupees Three Crore Twenty Lakh only).
Facts, dates, quantum. Notice what’s absent: no argument about why the logs are reliable, no anticipation of your opponent’s defence. You are identifying a dispute, not winning it. The approximate figure is what allows anyone later to test when this claim arose.
- Our Client’s communications dated 14 October 2025 and 8 December 2025 called upon you to make good the said losses. You have failed to do so, and have instead disputed the reliability of your own temperature logs.
Establish that a dispute exists and that it has crystallised. This paragraph is doing limitation work.
- Disputes having accordingly arisen between the parties, our Client hereby invokes Clause 19 of the Agreement and calls upon you to refer the said disputes to arbitration. Clause 19 reads as under:
“Any dispute arising out of or in connection with this Agreement shall be referred to and finally resolved by a sole arbitrator appointed in accordance with the Arbitration and Conciliation Act, 1996. The seat of arbitration shall be New Delhi and the venue shall be Gurugram. The award shall be final and binding on the parties.”
This is the paragraph that makes the document a Section 21 notice. The clause is reproduced verbatim and the word “invokes” appears. In Alupro, its absence was fatal. If you cut everything else, keep this.
- In terms of Clause 19, our Client nominates Mr./Ms. [Name], [qualification and address], as the sole arbitrator, and calls upon you to confirm the said appointment within fifteen (15) days of receipt of this notice. The seat of arbitration shall be New Delhi and the venue Gurugram, as provided in Clause 19.
Nominate. Do not appoint. A unilateral appointment is the error Alupro was decided on, and it converts a good claim into a jurisdictional fight. Seat and venue are restated because the clause distinguishes them, and the seat is what fixes supervisory jurisdiction in the Delhi courts.
- Our Client further places on record that by an order dated 3 February 2026, the [Court] has restrained you from releasing the consignments presently in your custody, and that this notice is issued in furtherance of those proceedings.
Where you hold interim relief, say so. Under Regenta, the ninety-day period under Section 9(2) runs from receipt of this notice, so the notice is the document that discharges that obligation. Putting the order on record links the two.
- Kindly take notice that the foregoing is not a complete recitation of the facts, nor a waiver of any right, remedy or claim, legal or equitable, available to our Client, all of which are expressly reserved. This notice is issued strictly under Section 21 of the Arbitration and Conciliation Act, 1996, and does not go into the merits of the disputes.
The reservation of rights, and an express statement of the statutory basis. Bhagheeratha confirms you’re not confined to the claims raised here, but a reservation costs one paragraph and removes the argument entirely.
- Should you fail to respond within fifteen (15) days of receipt, our Client shall be constrained to seek appointment of an arbitrator under Section 11 of the Arbitration and Conciliation Act, 1996, at your risk as to costs and consequences.

State the consequence of silence, and name the provision you’ll invoke. LawSikho’s walkthrough of the same document takes a different fact pattern through the same structure, and is worth reading alongside this one for a second angle on the drafting.
Drafting errors that cost claims
Five recur, and each traces to a decided case or a live limitation problem.
Never referring to the arbitration clause. The Alupro error. A notice that recites grievances without invoking the clause is a demand letter, and it starts nothing.
Appointing instead of proposing. Also Alupro. A unilateral appointment denies the other side the opportunity to accept, contest, or settle, and it’s the reason that award was set aside.
Conflating a contractual demand with a Section 21 request. A cure notice under a payment clause does the contract’s work. It doesn’t do Section 21’s. Send both if the contract requires it, and keep them as separate documents.
Serving at the wrong address. Section 3 tells you where a notice is deemed delivered, and the clause usually tells you where the parties agreed it would go. Ignore the clause and you’re litigating receipt.
Quantifying the claim so loosely that limitation can’t be tested. “Damages to be quantified” is not a claim value. It’s an invitation to argue that no identifiable dispute was ever referred.
Serving the notice and proving receipt
Service is where a well-drafted notice goes to die, because receipt is the operative event and receipt is what you have to prove.
Section 3 of the Act sets the default rules. A written communication is deemed received if delivered to the addressee personally, or at their place of business, habitual residence, or mailing address. Where none of those can be found after reasonable inquiry, a communication sent by registered post to the last known place of business or residence is deemed received. And the communication is deemed received on the day it’s so delivered.
So your proof of service is your proof of commencement. Keep the acknowledgement due card, the courier’s delivery report, the email delivery receipt. In a limitation fight three years out, that scrap of paper is the case. Frankly, this gets overlooked: firms draft immaculate notices and then file the AD card nowhere.
What about email and WhatsApp? Here the published guidance runs ahead of the case law, and it’s worth being precise. You’ll find M/s Lease Plan India Pvt. Ltd. v. M/s Rudraksh Pharma Distributor (Delhi High Court, 10 April 2024) cited across law-firm blogs for the proposition that a Section 21 notice can be served over WhatsApp. Read the order and that isn’t what happened. Arbitration in that case was invoked conventionally, by a legal notice dated 31 December 2022. What the court permitted by WhatsApp and email, after registered and speed post had failed, was service of court process in the Section 11 petition, to the addresses and phone numbers mentioned in the agreement. Useful, and a fair signal of judicial attitude to electronic service. But it is not authority that your Section 21 notice may go out by WhatsApp alone.
The distinction matters because of what Section 21 does. A court can cure defective service of its own process by directing an alternative mode. Nobody can retrospectively cure the receipt date of a Section 21 notice, because that date is your commencement.
So the recommendation here is unglamorous: serve by every mode the clause permits, simultaneously, on the same day. Registered post AD to the contractual address, email to the contractual email, plus whatever else the notices clause allows. Treat electronic modes as corroboration of receipt, not as a substitute for the mode your contract specifies. The marginal cost is a few hundred rupees. The marginal benefit is that receipt stops being arguable.
Replying to a notice invoking arbitration
A reply to a notice invoking arbitration should place your objections on record without conceding anything and without disclosing your defence. There’s no statutory obligation to reply at all, which makes the first question strategic rather than legal.
When is silence defensible? If your position is that no valid arbitration agreement exists, letting the claimant go to court under Section 11 and contesting the clause there is a coherent strategy. Otherwise, silence is expensive. It doesn’t stop the arbitration: the claimant simply moves under Section 11 and the court appoints. What silence does is forfeit your say in who that arbitrator is, and leave the tribunal with the claimant’s unanswered version of the dispute as the only account on record.
Before you agree to the claimant’s nominee, run the Fifth and Seventh Schedule checks. Ineligibility under the Seventh Schedule cannot be cured by agreement except by an express written waiver after disputes arise, and agreeing to a disqualified arbitrator now means litigating the award later.
The model reply, in skeleton
Subject: Reply to your notice invoking arbitration dated 20 February 2026
This reply is issued for and on behalf of Northline Logistics Pvt. Ltd. to your notice dated 20 February 2026 issued on behalf of Meridian Foods Pvt. Ltd.
At the outset, all allegations, claims and contentions in the said notice are denied. Nothing contained therein shall be deemed admitted by reason of non-traverse.
The general denial. It prevents your silence on any particular allegation being read as acceptance.
- Without prejudice to the above, the claims raised are disputed both as to liability and as to quantum. Our client reserves the right to advance its complete case, and to raise its counter-claims including its claim for outstanding service charges of Rs. 1,08,00,000, before the arbitral tribunal.
Flag the counter-claim. Don’t plead it. This is where most respondents over-write, arguing the merits in a document nobody will decide.
- With respect to your nomination of Mr./Ms. [Name] as sole arbitrator, the same is not acceptable. Our client proposes Hon’ble Mr./Ms. Justice [Name] (Retd.), [former court], as the sole arbitrator, and calls upon you to confirm within fifteen (15) days of receipt.
Reject with a counter-proposal. A bare rejection just delivers both sides to a Section 11 petition.
- This reply is without prejudice to all rights, remedies and defences available to our client under the Agreement and in law, none of which are waived. Nothing herein constitutes an admission of liability.
Two habits separate a good reply from a bad one. Answer the appointment, and say nothing about the merits. The first is the only thing the reply can actually achieve. The second is a gift you don’t have to give.
Drafting of this quality is also a portable skill, and one that increasingly travels: Skill Arbitrage’s piece on contract drafting for foreign clients looks at how Indian lawyers price and package drafting work for clients outside India.
Frequently asked questions
Is a notice invoking arbitration mandatory?
Issue it, always. In Bhagheeratha Engineering v. State of Kerala (2026), the Supreme Court held there is no mandatory prerequisite for a Section 21 notice and that failure to issue one is not fatal where the claim is otherwise valid and the disputes arbitrable. But skipping it forfeits your limitation anchor and your Section 11 route, so the ruling is protection against an error, not a strategy.
When do arbitral proceedings commence under Section 21?
On the date the respondent receives the request to refer the dispute to arbitration, unless the parties have agreed otherwise. Receipt, not dispatch, is the trigger.
Can a notice invoking arbitration be served by email or WhatsApp?
Serve by the mode your notices clause specifies, and treat electronic modes as corroboration rather than a substitute. The Delhi High Court has allowed WhatsApp and email service of court process to contract-specified addresses where conventional service failed, but that is not authority that a Section 21 notice may be issued electronically alone. Since receipt fixes commencement, registered post AD to the contractual address remains the safe course.
Is a fresh notice needed after an award is set aside under Section 34?
Generally no, where the dispute remains the same and the other party is already aware of it. The safer course, if limitation is anywhere near live, is to issue one.
Can an application under Section 8 work as a Section 21 notice?
No. A Section 8 application asks a court to refer parties to arbitration. It does not amount to a request under Section 21 and does not fix the date of commencement.
What happens if the other party ignores the notice?
The claimant applies under Section 11 for appointment of an arbitrator. Silence doesn’t prevent the arbitration; it only removes the respondent’s say in who is appointed.
